TO 4.ALL W'HOM-AITMAY GONCERN: Y

Be it known that I, GEORGE Turris, of Salem, in the county of Washington, and State of New York,' have -invented a new and improved Music-Rack; and I do hereby declare the followingto` be a full, clear, and exact ,description 'of the same, reference being hereby had to theaccompanying drawings, which form and .make ,a part of this specification.

Like letters represent' and refer to like or corresponding parts. A Figure 1 is a perspective view of my `said improved music-rack, showing the various parts the1eof, each more, fully hereinafter described and set forth.

'Figure 2 is'also a perspective view of my said invention, showing the same as it would appear-when. the

leaves or folds, O, were open, as, fully hereinafter described and set forth. A

Figure 3 is a view of the bottom ofthe bed plate, A, showing th'e mechanism by which the leaves or folds,

O, are-operated, substantially in the manner and by the means hereinafter. described and set forth. l

Figure 4 is a cross-section through the cylinders D, D', and D", and clearly-showing the construction'-andl voperation of the same, as fully hereinafter described and set forth. v

The nature of my said invention and improvements consists' in so constructing' amusic-rack or frame, that when the same is invuse, the music placed thereon may be readily turned by the person playing thevins'trlument,

without any inconvenience; substantially vin the'mannier'and by the means hereinafter described and set forth.

It also consists in the employment of the levers C,C', and .0", in connection withY the cylinders D, D','and

D", teach constructed,P combined, and operated in the' manner and for the purposes substantially as hereinafter.

described and set forth'. Y

` It also consists in the employment of the springs E, E', and E", and F, F', andF", by means-of which the levers Clare operated so as-to turn the leaves or' folds of the music-rack, substantially in the manner and for the purposes hereinafter fully described and set forth. d I l A To enable others skilled in the art to which my invention relates to make and use the same, I will here proceedto describe the construction and operation of the same, which is as follows, to Vwit: A, figs'. 1, 2, and 3,

. is the bed-plateof my said music-rack, and maybe made of any wood ormetal deemed best.- At the rear end thereof is the upright or bar 'B, which is securely fastened to the said plate A by any means thought best. Around the bottom of said upright, D, are placed the cylinders D, Df, and D", constructed substantially as shown at figs. 3 and-4, in the accompanying drawings, havingattaehed at their lower ends, and under the bed plate A, the' cog-wheels H, H',- and H". The upper'cylinder D passe's through both the cylinders D and D", und is connected at its lower end vwith the under cog-wheel H". The second and middle cylinder D'is formed around the upper cylinder D, butpasses through the lower cylinder D", and is connected at its low-er end with the middle cog-wheel H', while the lower cylinder D" surrounds both the upper ones, D and D',4 and is connected at its lower end with the upper cog-wheel H. It is obvious that as many cylinders and wheels can he used as may be required, if constructed uponthe principle and in the manner above described. Upon the underside, and at about the centre of the bedplate A, I attach, by'means of a pivot, I, the levers .0, C', and C", or their equivalents, the said pivot I allowing them to work freely both ways. The rear ends'of each of the said levers C, 0, and C",'are notched so as to correspond with the cog-wheels, H, H', and H", into which they work, for the purpose of turning the said cylinders D, D', and D". At the other ends of the said levers C, C', and-C",

are attached the thumb-pieces J, J', and J", which pass through the bed-plate A, and by means of which the said levers are worked, which, in their turn, operate the said cylinders D, D', and D". E, E', and E, are

suitably-constructed springs,- securely fastened at one endpto the bottom of the bed-plats A, and-Which press against and operate the said levers C, C', and C", substantially as hereinafter described and 4set forth. F, F', and F", are also springs whichv'are for the purpose of holding the levers C, C', andC", in their proper place and position when the same are set in the manner and for the purposes hereinafter described. The said springs F, F', and F", are also operated by'means of thumb-pieces K, K',A and K", which pass through the said bedwww... .A f,... a

plateiA, in .the manner and for thepurposes hereinafter described. ToA each of the cylinders surrounding lthe upright or bar B, is attached a suitably-shaped frame o'r de vice, into which the. music may be plaeed. Any con- 'struction thereof maybe adopted that wil'lbest answer the required purpose; -The various partsof my said improved music-rack may bemade of any material deemed best, and of such size, strength, and quality as future experiment may indicate. I l l When it is desired to use my said invention for thep'urpose which itis intended, the manner of operating is as follows: The music desired to be played is placed in the'raek or frame which is attached to the cylinders,

thel said cylinders are then set by means of the levers C, Q', and C, which are heldin the position they are Aset by means of the springs F, F', andF, which catch in slots en t .on the under sideof the said levers, as

shown at iig. 3 in the accompanying drawings. When it is desired to turnlthe first leaf of the music, the thumbpiece K is pressed downward, which pushes the spring-l` out of the slot in the lever C; the springE, thenacting upon the said lev'er, presses-it b aek, thereby .turning the cylinder D, to which the, frame'isattached inY which. the music is placed. This sume operation with the second lever will turn the second leaf of the music, and so on, as many levers may be used asdesi'red, according to the number of 'leaves desired to turn. By this means I am enabled to construct amnsic-raek, in which -the music placed vtherein maybe turned without any inconvenience to the player, as a slight -pressure upon the thumb-piee-esK, which are designed to be placed immediately in ,front 'of the player, will turn lthe different leaves of the music, substantially as. herenbefore described and set forth.

v Having thus described the nature of my said invention and improvements, whatI claim as my invention, and desire to secure by IiettersPatent of the United States, is'

' 1. An improved music-rack or machine for turning music, constructed in the manner 'and for the 'purposes substantially as herein described and set forth. 'l

2. I claim the'notched levers C, C', and C, and the cog-wheels H, H', and H, and the cylinders D, D', and D,4 in combination with'and operating' the leaves or folds O of a music-raek or frame, substantially as hereinbefore fully described and set forth.

3. I claim the upright or-bar B, and the cylinders D, D', and'D, and'levers C, C', and C", in combination with a music-rack or frame, substantially as herein fully describedl andset forth.

4. I claim the combination of the levers C, C', and C, operated bythe springs E, E', and E, and RVF',

-and F, with the cog-wheels H, H', and H, cylinders D, D', 'andD,and upright or bar B, each heing'constructed and operated in the manner and'for the purposes substantially as herein fully described and set forth.

In testimony whereof, I have hereunto set my hand, this 9th day of April, 1867.
